this all sounds like me- i have for the past three years been asking myself if i was having heart symptoms or life symptoms. even today- im still asking . i get a little short of breath, have some weird vibrations occasionall, and im REALLY tired -espe in the afternoons, but its all so fleeting .. at hte same time, my mean gradient is now 43 and my peak 98 with valve area of .5! so im severely severe i guess but ican still carry my kids around, do my chores, have fun with friends and live pretty normal...maybe because im short my heart has accomodated my life. this is common i htink. but i agree with the majority here...the time to act is now- before the walls of the heart thicken or enlarge, before the symptoms become definitive heart symptoms and not just easily explained away by stress or exercise.
